Abstract
The invention discloses a heat shrink tube expansion system. The heat shrink tube expansion system comprises a conveying roller wheel set, a heating furnace, an expansion mold and a pulling roller wheel set in sequence, wherein at least one driving roller wheel set for driving a heat shrink tube to be expanded is arranged in the heating furnace. According to the heat shrink tube expansion system, the driving roller wheel set is arranged in the heating furnace and is used for applying conveying pulling force to the heat shrink tube to be expanded in the heating furnace, so that a semi-finished product of the heat shrink tube to be expanded can be effectively pulled into the heating furnace, the axial stretching deformation caused by a long distance between the conveying roller wheel set and the pulling roller wheel set is avoided, the expansion can be stabilized, and the product quality is improved.
Description
Technical field
The present invention relates to a kind of expanding thermal shrinkage tube system.
Background technology
Heat-shrink tube generally by extrude, irradiation and expansion finish its production.When expansion, heat-shrink tube is finished expansion through dilatation mold through heating under inflated condition.
The expanding thermal shrinkage tube system comprises conveying roller wheels, heating furnace, dilatation mold and the carry-over pinch rolls wheels that sequentially arrange, and wherein, the conveying roller wheels are arranged at outside the heating furnace.For avoiding thermal loss, heating furnace seals its entrance.In when expansion, heat-shrink tube semi-finished product to be expanded under inflated condition through the conveying roller wheels carry, the heating and finish the expansion of heat-shrink tube through dilatation mold to the heating furnace of the traction action of carry-over pinch rolls wheels.
Yet, above-mentioned expanding thermal shrinkage tube system is when the expanding thermal shrinkage pipe, because heating furnace is longer, the entrance of adding heating furnace has sealing, heat-shrink tube semi-finished product to be expanded have drag effect when the entrance by heating furnace, this just cause the conveying roller wheels be difficult to will be to be expanded the heat-shrink tube semi-finished product especially during tubule for example Ф 1 heat-shrink tube be delivered in the heating furnace, if add the draw power of the carry-over pinch rolls wheels in rear area, then can be owing to its diameter is less, easily axial tension distortion under the draw of the conveying of conveying roller wheels and carry-over pinch rolls wheels, this can cause heat-shrink tube not meet production specification.
Summary of the invention
The object of the present invention is to provide and a kind ofly heat-shrink tube semi-finished product to be expanded can be delivered in the heating furnace and be difficult for the axial tension distortion during expansion, can stablize the expanding thermal shrinkage tube system of expansion.
For achieving the above object, the invention provides a kind of expanding thermal shrinkage tube system, comprise the conveying roller wheels, heating furnace, dilatation mold and the carry-over pinch rolls wheels that sequentially arrange.Wherein also be provided with the driven roller wheels that the expanding thermal shrinkage pipe is treated at least one driving in the heating furnace.
Preferably, also be provided with the driven roller wheels that the expanding thermal shrinkage pipe is treated in driving between described heating furnace and the dilatation mold.
As mentioned above, expanding thermal shrinkage tube of the present invention system arranges drive roller wheel in heating furnace, this drive roller wheel is treated expansion in heating furnace heat-shrink tube applies conveying tractive force, the phenomenon that is difficult to enter heating furnace of avoiding the entrance resistance because of heating furnace to cause, can effectively heat-shrink tube semi-finished product to be expanded be drawn to heating furnace, avoid conveying roller wheels and carry-over pinch rolls wheels owing to the axial tension distortion that distance causes, can stablize expansion, improve the quality of products.

The specific embodiment
By describing technology contents of the present invention, structural feature in detail, being realized purpose and effect, give in detail explanation below in conjunction with embodiment.
Embodiment 1
See also Fig. 1, the embodiment 1 that it has disclosed expanding thermal shrinkage tube of the present invention system comprises the conveying roller wheels 1, heating furnace 2, dilatation mold 3 and the carry-over pinch rolls wheels 4 that sequentially arrange.
Be provided with at least one driven roller wheels 5 in the heating furnace, in the present embodiment, driven roller wheels 5 are two groups, and certainly, the quantity of driven roller wheels 5 can be set to the varying numbers such as 1 group, 3 groups as required.
Expanding thermal shrinkage tube of the present invention system when using, heat-shrink tube 6 ' to be expanded under inflated condition through the traction action of conveying roller wheels 1, driven roller wheels 5, carry-over pinch rolls wheels 4 to heating furnace 2 interior heating and finish the expansion of heat-shrink tube 6 through dilatation mold 3.
In sum, expanding thermal shrinkage tube of the present invention system is in the heating furnace 2 interior drive roller wheel 5 that arrange, this drive roller wheel 5 is treated expansion in heating furnace 2 heat-shrink tube applies conveying tractive force, the phenomenon that is difficult to enter heating furnace of avoiding the entrance resistance because of heating furnace to cause, can effectively heat-shrink tube semi-finished product 6 ' to be expanded be drawn to heating furnace 2, avoid conveying roller wheels 1 and carry-over pinch rolls wheels 4 owing to the axial tension distortion that distance causes, can stablize expansion, improve the quality of products.
See also Fig. 2, it has disclosed the embodiment 2 of expanding thermal shrinkage tube of the present invention system, and the present embodiment is similar to Example 1, its difference is: also be provided with driven roller wheels 5 between heating furnace 2 and the dilatation mold 3, this can further be avoided the axial tension distortion, and stable expansion is improved the quality of products.
The present invention is not limited to the above-mentioned specific embodiment, and those skilled in the art that also can make multiple variation accordingly, but any and the present invention are equal to or similar variation all should be encompassed in the scope of claim of the present invention.
Claims (2)
1. an expanding thermal shrinkage tube system comprises the conveying roller wheels, heating furnace, dilatation mold and the carry-over pinch rolls wheels that sequentially arrange, it is characterized in that: be provided with the driven roller wheels that the expanding thermal shrinkage pipe is treated at least one driving in the described heating furnace.
2. expanding thermal shrinkage tube as claimed in claim 1 system is characterized in that: also be provided with between described heating furnace and the dilatation mold and drive the driven roller wheels for the treatment of the expanding thermal shrinkage pipe.
